" CAR-PROPELLER.

SPECIFICATIONforming part of Letters Patent No. 256,292, dated April 11, 15.82.

' Application tiled February 23, 1882. (No model.)

To all whom it may concern.- v

Be it known that I, JACOB H. COLE, of Danville, in the county of Montour and State of Pennsylvania, have invented certain new and useful Improvements in Oar-Propellers; and Ido hereby declarethat the following is a full, clear, and exact description of the in-` scribed, and then specifically pointed out in the claims. i

In the annexed drawings, which fully illustrat/e my invention, Figure 1 is a plan of a car frame or truck, showing the manner of applying myinvention. Fig. 2 is a vertical longitudinal section ot' the same on the line w x of Fig. 1. Fig. 3 is asimilar section on theline y y of Fig. 1. Fig. 4 is a transverse section ou the line z z ofFig. 1.

Y Like letters indicate like parts in the several views.

AA represent the side pieces, and A A the cross-pieces, composing the frame, upon which rests the car-body or platform.

To the side beams are attached the hangers or bearings B B, in which are journaled the axles C O', that carry the track-wheels D D.l

The main power-shaft E isjournaled in bearings a, a, and carries the cogged wheels F F,

each of which is provided on one side with a ratchet, b.` These wheels F are provided on each sidcggwith flat steel springs c c, ot' great strengthgand elasticity, one endofeach spring being attached to thehub or collar of the wheel, while the other end is secured inany suitable manner to across-beam of the car-frame. The springs c o are coiled, as shown in Fig. 2, and when properly wound are capable of propelling the car, as hereinafter explained.

In the drawings I have shown only two cogged orspur wheels on the shaft E; but itis obvious that any suitable number may be employed.

The cogged wheel F on each side is adapted to gear with a small cogged wheel, G, which is journaled in a bracket or hanger, d, attached to one of the cross-pieces A. Only one of the cogged heels Gis shown in the drawings; but any suitable number may be employed corresponding with the number of the larger cogged wheels F, with which they gear. The small cog-wheel G is journaled on an eccentric shaft, e, that is provided with a crank-arm, e',

which is attached to a rod,j', that isconnected with the lower end of a'lever, g, which is pivoted in suitable bear-ings at one end of the cari'rame. The rod f is provided with a pin,f, which is adapted to engage with the end of a bent rod, h, that is looped at one end to the rodf, While its opposite end is attached to a pawl, z', which is pivoted to a cross-bar of thc frame, and is'V held to contact with the ratchet ries near its center a large cogged wheel, K.

These spur-wheels H and K are loose on the v shaft I, and are provided .on one side with spring-pawls m, by which they are connected with the ratchet-wheels u, which are secured to said shaft. The cog-wheel K meshes with a cog, L, which is attached to and forms part of a wheel that is journaled on the axle C, and which wheel is provided also witha ratchet, M, and miter-gear N, the cog L, ratchet M, and miter-gear N being integral with each other, and together constituting one wheel, which is journaled loosely on the axle.- The miter-gear N is connected by an intermediate gear, P, with the miter-gear N', which is also journaled loosely on the axle O. The intermediate gear, P, is journaled on an arm, p, which is attached to the car-frame, and is provided.y

at its lower end with a collar that encircles the axle between the gears N and N.

' Slidin g on the axle C, and connected there- IOO ing arms Q Q of a transverse sliding bar, B, which is supported in a bracket, S, attached to the car-frame. The barltis caused to slidc transversely in the bracket .S by means of a lever, T, so as to alternately open and close the clutches as required. The jaw s of either clutch, when thrown into gear with its corresponding jaw, s', is held to its engagement therewith by mrans of a coiled spring, t, arranged on the axle.

A pawl, U, is pivoted in the end of an arm, V, for the purpose ot' engaging,when required, with the ratchet M, so that when the lever T is thrown to thtl center in opening the clutches on both sides thc engagement of the pawl U with the ratchet M will prevent the power of the coiled springs from being expended. The pawl U is raised from its engagement with the ratchet M by means of a rod, a', one end of which is attached to the pawl and the other end to a bent arm, b', that is pivoted to the frame and adapted to be raised by an arm or pin, c', attached to the lever T.

The operation of my car-propelling device is as follows: The spring-wheels F F are actuated by means of steam or horse power applied to the projecting ends of the shaft I, so as to coil the springs c c through the medium of the gears H and G. It will be seen that when the shaft I is provided with any number of loose gears H and their fixed ratchets n, by shifting any of the gears H, so as to disengage their pawls from their respective ratchets, a limited number of the spring-gears F F may be actuated, or all may be operated upon at once, so as to wind any desired number of the coiled springs, according to the amount of power required. When the pawls i are retracted from their engagements with the ratchets b, attached to the wheels F, the tension ofthe springs c c will cause said wheels to rotate, so as to actuate the spur-wheels G, with which they mesh. The gears G in turn actuate the gears H and shaft I, thus causing the large spur-gear K to rotate and impart its motion to the cog L on the axle C. By causing the lever T to bring the clutches s s' into engagement on the right or left side the car will thereby be propelled forward or back, as desired. If the lever T is brought to a "ertical central position, so as to cause the pawl U to engage with the ratchet M, both clutches being now open, the engagement of said pawl with its ratchet will prevent the rotation of the gears N N', and thus preventthe useless expenditure of thepower stored in the coiled springs when the ear is stopped. By throwing the lever T from one side to the other the motion of the car may also be reversed at will. In stopping the car the lever g is caused to throw the pawl i into engagement .with the ratchet b, the same motion of the 1ever g also actuating the eccentric-shaft e, so as to throw the spur-wheel G out of gear with the direction the various gears may be made to coact, so as to canse the momentum of the car to react upon and partially wind the springs for further action.

Attached tothe frame A is a standard, B', in which is journaled a pulley, d', the shaft of which carries an index, g'. This pulley is connected by a band, h', with a pulley, 7c', on the hub of one of the wheels F, so that the revolution of said wheel will cause the index g'toindicate upon a dial, m', the extent to which the power ofthe springs c is exhausted.

Havingthus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a car-propeller, the combination, with the shaft E, having spur-wheelsl F, provided with ratchets i) and springs o, and shaft I, having loose spur-wheels H and K, provided with spring-pawls m, and fixed ratchets n, of one or more spur-wheels,G,journaled upon an eccentricshaftorshafts supported in suitable brackets, a pawl,1'., adapted to engage with the ratchet b, and a lever, g, and rodsfand h, connecting with said pawl and with av crank, e',on the eccentricshaft e, substantially as shown and described.V

2. In a car-propeller, the combination of the frame A and A', the shaft E, having spurwheels` F, provided with ratchets b and springs c c, the spur-gears G, journalcd upon eccentricshafts e, having crank-arms c', the shaft I, havingloosespur-gearsH K, provided with springpawls m m, and fixed ratchet-wheels u mkeyed to said shat't,the axle C, havingspring-clutches s s, gears L, M, N, and N', the gears L and N' being provided with clutch-jaws s' s', the intermediate gear,P,connectin g the gears N N', the sliding bar R, having arms Q Q, lever T, having pins c', adapted to retract the pawl U from its engagement with the ratchet M, and the leverg and rods f h, for retracting the pawl z' and raising the cog G out of gear, all substantially as shown and described.

In testimony thatI claim the foregoing as my own I have hereto aftxed my signature in presence of two witnesses.
